Baron Aerospace was a nascent aerospace firm, now converted into a worker syndicate by the United Eruvean Society. Their first spacecraft, the "Pisces," was created as a successor to previous "Fusion"-derived supply spacecraft. It is fully integrated into the existing Fusion Launch System, thus able to be launched on easily-produced Fusion LV rockets, and freeing up Argolev RSC's tooling to focus on producing TSS spacecraft.
At least that's the lore, in reality it's something I knocked together pretty quick based on some craft I made for Juno: New Origins. It's the first "original" spacecraft I made for my game though, so it'll always have a place in my heart.
